Original application filed May 26, 1916, Serial No. 99,992. Divided and this application filed March 21,

i 1918. Serial No; 223,848.

1 '0 all whom it may concern:

Beit known that I, WILLIAM SEWARn BAmn, a citizen of the United States, residing at Decatur, in the county of Macon and State of Illinois, have invented certain new anduseful Improvements in Husking-Machines, of which the following is a description.

My invention belongs to that general class of devices known as corn harvesters, and re lates particularly to an improved form of snapping rolls which may be used with such other cooperating mechanism as be de sired. This application is a division of my Patent No. 1,295,254, dated February 25, 1919. The invention has among its objects the production of a simple, improved, efficient, durable and satisfactory snapping roll of the kind described for use wherever found applicable. Other objects and ad.- 'antages of the construction herein shown and described will be obvious to those skilled in the art from the disclosure herein given.

To this end, my invention consists in the novel construction, arrangement and combination of. parts herein shown and described and more particularly pointed out in the claims.

In the drawings, wherein like reference characters indicate "like or corresponding parts, I r

Figure 1 is a plan view of a pair of cooperating snapping rolls;

Fig. 2 is an enlarged plan view thereof; and V F ig. 3 is a cross section thereof taken sub stantially on line 3-3 of Fig. 2.

Referring to the drawings, I show a pair of cooperating rolls 1-1, which are each formed with spiral grooves as at 2 so as to form recesses 3 and raised portions 1, the arrangement being: such that when the rolls are rotated, the raised portions 4 of one will fit into the recess 3 of the other. As most clearly shown in Fig. 3, thetrolls are cut out or grooved longitudinally as at 5, so as to provide longitudinal engaging portions or shoulders and spaces in alternation therebetween. There may be as many out out or grooved portions 5 as desired, but I generally prefer four, substantially as shown, so that the rolls are practically cross-shaped or like an X. On the raised portions and in the recesses I provide a plurality of cups or depres sions 6, which are preferably arranged at the corners, substantially as 'shown in Fig. 2. In eachrecess 3 I preferably provide a stud or ra sed portion 7, and a cooperating depress on 8 in theraisedportions l, which depresslon cooperates with the stud 7 when the rolls'are rotated. In this connection I also prefer to slightly taper the studs 7 as shown in F 3.

The rolls are of the desired size and shape, and are supportedat their forward'ends (see Fig. 1) by the bearings 10 and 11, or their equivalents, and at the rear end by bearings 12 and 13, or their equivalents, which carry the shafts 18 and 19 arranged to drive the two rolls. Iprefer to support the rolls, or at least one of the rolls so that one may yield to permit, separation in case of necessity. The same, however. are normally maintained in operative relation by the springs 14:, or their equivalents, cooperating with the bearing boxes and the frame or suitable brackets 15. I have not considered it necessary to completely illustrate in detailthe specific frame construction and brackets employed. ()neof the shafts, as shownshaft 18, may be driven by a gear 22, and through the gears 20 and 21 drive the other shaft 19. It may be mentioned that the gears 20 and2l are provided with long teeth so as to permit movement of the rolls relative to each other due to the movable boxes 11 and 13.

In operation, the rolls being driven in oppositedirections, asindicated by the'arrow in Fig. 1, they willfeed the stalks rearwardly and downwardly due tothe engagement of the studs and: depressions therewith. The shoulders provided by the cut out portions or grooves 5, form a most effective means to grip and grasp the stalks to force them throughbetween the rolls while the earsare snapped therefrom. '7

.Having thus described my invention. it is obvious that various immaterial IIlUCllfiCR: tions may be made in the.sainewithoutda parting from the spirit of my invention; hence I do not wish to be understood as limiting myself to the exact form, construction, arrangement and combination of parts herein shown and described or uses mentioned.

What I claim as new and desire to secure by Letters Patent isg-e 1. In combination in a husking machine,

a pair of stalk engaging rollers, said rollers I across, the raised portions of said rollers formed by said channels having cutout parts to provide on said rolls a plurality ofs'ubstantially,rectangular shaped extensions, the

rectangular shaped extension of one roll fitting in the corresponding pocket in an ad'- "jacent roll i'ormed by said cutout portions.

2. In a corn husking device, a pair of rolls adapted to operate in unison, each of said rolls having a spiral groove producinglseparated raisedporti'ons, and longitudinal cutout portions extending longitudinally and entirely across, theroll forming the raised portions into a rectangular shape, and the raised portions of one roll entering the grooves formed in the other, substantially as described. a

3. In a corn husking device and in combination, a pair'of rolls rotatably mounted andyieldingly maintained in operative rela tion, said rolls being substantially crossshape in cross section and having interfitting projecting and socket portions adapted to interengage at the ends of the cross. I 4. In combination, in a husking device, a pair of snapping rolls" adapted to rotate in unison in opposite directions, means for mounting one of said rolls to enable the same to yield relative to the other, each of sait rolls having spiral grooves therein and a plurality of longitudinal cutout portions intersecting the groove to produce cooperating shoulders, substantially as described.

j 5. In a cornharvester-and in combination, a pair of rolls rotatably mounted and yield ingly maintained in operative relation, said rolls being'provided with depressions and raised parts arranged longitudinally? the rolls, the raised portions being provided 7 with diagonally positioned plates thereon,

the meetingraised portions on the two rolls being provided with cooperating studs and depressions, and the depressed portions on the two rolls cooperating together to form shoulders to engage the stalks between the cooperating parts of the two rolls.

6. In a corn husking device, a pair of snapping rolls and means for operating said rolls in opposite directions, each ofsaid rolls having spiral grooves therein forming pro jecting parts, longitudinal cutout portions extending across said rolls and'ext'ending below the base of the grooves, the raised'portions of each roll consisting of a plurality of rectangular shaped parts adapted to enter the grooves of the adjacent roll.

7. In a corn husking device, a pair of snapping rolls and means for operating said rolls in opposite directions, each of said rolls having. spiral grooves therein forming projecting parts, longitudinal cutout portions extending across sald rolls and extending fitting tongue and socket portions, subetantially as described.

8. In a cornhusking device, a pair of snapping rolls and means for operating the same, each of said rolls having spiral grooves therein, and a plurality of longitudinally disposed cutout portions extending entirely across said rolls below the base of the grooves, the projecting part of one roll formed by the grooves fitting the grooves in the opposite roll.

9. In a corn husking device, a pair of snapping rolls'and means for operating the same, each of said rolls having spiral grooves therein, and a plurality of longitudinally disposed cutout portions extending entirely across said rolls below the base of thegrooves, the projecting part of one roll formed by the grooves fitting the grooves'in the opposite roll. and stud and socket interfitting parts carried by said projecting portions and the 'base of the grooves.

' 10. In a corn husking device, a pair of snapping rolls and means for operating the same, each of said rolls having spiral grooves therein, and a pluralityof longitudinally disposed cutout portions extending entirely across said rolls below the base of the grooves,;the projecting part of one roll formed by'the grooves fitting the groove in the opposite roll, and stud and socket interfitting parts carried by said projecting portions and the base of the grooves, the proecting portions formed by the spiral grooves beingin the nature of aplurality oi" separated rectangular shaped parts.
